As well as every other store, Aldi has some wire put-together shelves on sale now. These are the same shelves I bought at Shopko six years ago when we built our new house to use in my son's closet. They are held together with a circular joiner that is supposed to keep the shelves together in whatever shape you need. I found that the circles were not strong enough to hold them together, however, I used small zip ties (cable ties) or whatever you call them to secure the shelves and they have held together wonderfully. I found some more at a yard sale a few years ago and I'm using them in my sewing room closet. The weight of the fabric was too much for even the zip ties, but I used the circles to screw the whole business to the studs at the back of the wall and they are plenty sturdy now. I think they are a good buy with the extra security, otherwise they won't hold up with weight on them. Just passing along some experience.
